Pokemon GO now seems to turn off the “Sightings” list and disables spawns at high speed

Pokemon GO players have come across a new change within the mobile app. It seems that, as of a couple of days ago, the “Sightings” nearby list turns off, and Pokemon do not spawn when going above a certain high speed.

Forbes asked Niantic for a comment about the situation, but no response has been provided thus far. It’s currently unclear if this is a bug or an intended change. However, we do know that Niantic made it so Pokemon GO warns players about using the app while driving with an update released a few months ago.
